Design DC Systems at Record Speeds

From first sketch to full topology — prototype, collaborate, and iterate with your team in real-time.

Prototype in Minutes

Sketch complete concepts in minutes by dragging and dropping your components.

Chat Channels

Say goodbye to scattered communication across emails, messages, and meetings. All discussions are stored with your design, creating a complete record of decisions and feedback.

Product Catalog

Find the products you need that fit your design. Search by product type, manufacturer, or specifications.

Annotations

Mark up your single line with logos, equipment photos, groups and notes — keep context next to the topology.

No credit card or download needed.

Advanced Features

Validate with Real Physics

Run power flow simulations, validate against IEC and NEC standards, and size your cables — all backed by real engineering models.

Power Flow Simulation

Simulate how your system behaves under different conditions and optimize your design.

Wire Sizing

Let our wire sizing engine suggest or validate your wire sizes according to IEC and NEC standards.

Fault Simulation

Run short-circuit scenarios across your DC system and find the perfect protection devices.

Live Data

Stream real measurements from a commissioned site back into the same diagram you designed.

No credit card or download needed.

DC Expert Online

Validate with DC Experts
